Effects of unilateral sinonasal surgery on sleep-disordered breathing

Abstract

Aims/objectives: To examine the effects of surgery for unilateral sinonasal lesions on sleep-disordered breathing (SDB).

Material and methods: Oxygen desaturation index (3%ODI) as a marker of SDB and bilateral/unilateral nasal resistance were measured before and after surgery for 18 patients with unilateral sinonasal lesions. Various parameters were compared between those who achieved 60% or less decrease of 3%ODI and those who did not.

Results: Bilateral nasal resistance as well as that of the surgical side five days after surgery was significantly lower than those of pre-operative value. Preoperative 3%ODI (times/hour) was 10.08 ± 7.32, which significantly decreased to 7.67 ± 5.79 five days after surgery. Even in unilateral patients, sinonasal surgery could reduce the bilateral nasal resistance, resulting in a decrease in 3%ODI. Age was younger and postoperative nasal resistance of the surgical side was significantly lower in the group who achieved 60% or less decrease in 3%ODI than those who did not.

Conclusions and significance: SDB is influenced by even unilateral nasal obstruction. Surgery for unilateral lesion can improve the respiration during sleep as well as bilateral nasal resistance. Favorable outcome by surgery could be brought about in younger patients and those for whom sufficient improvement of nasal resistance was expected by surgery.

目的：检查单侧鼻腔鼻窦病变手术对睡眠障碍呼吸（SDB）的影响。

材料与方法：对18例单侧鼻腔鼻窦损伤患者在手术前后测定作为SDB和双侧/单侧鼻阻力的标志的氧饱和度下降指数（3％ODI）。将达到60％或更低的氧饱和度下降指数的患者和未达到的患者的各种参数进行比较。

结果：术后5天双侧鼻阻力以及手术侧鼻阻力明显低于术前。术前氧饱和度下降指数（次/小时）为10.08±7.32, 术后5天降至7.67±5.79。即使在单侧患者中, 鼻腔鼻窦手术也可降低双侧鼻阻力, 导致氧饱和度下降指数降低。达到60％或更低的氧饱和度下降指数的患者与未达到者相比, 年龄更小且手术侧术后鼻阻力明显更低。

结论和意义：SDB甚至会受到单侧鼻塞的影响。单侧手术可以改善睡眠呼吸以及双侧鼻阻力。通过手术, 对于年轻患者和那些预期可以通过手术改善鼻阻力的患者会带来有利的结果。
